I grew up on Mil Dots in the Marine Corp Sniper program however I prefer Minutes because the math is simpler for range estimation, and the windage formulas are already in minutes. The military uses Mils for sniping because Mils are used in artillery so most prospective sniper students are already loosely familiar with them. The only downside is most scope reticles which are calibrated in Minutes are designed for target shooting and are too thin (hard to see) for low light and / or tactical use. At the end of the day they both work equally well but I find Minutes easier to teach and use in the field.
I too am a mil/mil FFP in metres guy. I would say maybe its a Canadian thing but there are more people both North and South of the border who use MOA and yards, having said that I think the popularity of mil/mil FFP is slowly growing.
Like most of you I started in MOA and it took me a while to get the whole mil thing straightened out in my head but once I did I would NEVER go back to MOA. I worked out the numbers and theory on paper(well....after I stole it off the internet) and once I got comfortable with it I took it into the field and began to apply it at different ranges.
Does anyone have an update on the GW rangefinder? (will they offer it in mils?)
Life is short... Lets go kill something
